Lotion composition for imparting soft, lubricious feel to tissue paper

ABSTRACT

A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 5 to about 15% by weight. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an agent such as sorbitan stearates or N-cocoyl, N-methyl glucamide to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

This is a continuation of application Ser. No. 08/165,767, filed on Dec.13, 1993, now abandoned.

TECHNICAL FIELD

This application relates to lotion compositions for imparting a soft,lubricious feel to tissue paper. This application further relates totissue paper treated with such lotion compositions.

BACKGROUND OF THE INVENTION

Cleansing the skin is a personal hygiene problem not always easilysolved. Of course, the common procedure of washing the skin with soapand water works well, but at times may be either unavailable orinconvenient to use. While soap and water could be used to clean theperianal region after defecation for example, such a procedure would beextremely burdensome. Dry tissue products are therefore the mostcommonly used post-defecation anal cleansing product. These dry tissueproducts are usually referred to as "toilet tissue" or "toilet paper."

The perianal skin is marked by the presence of fine folds and wrinkles(sulci) and by hair follicles, both of which make the perianal regionone of the more difficult anatomical areas to cleanse. Duringdefecation, fecal matter is excreted through the anus and tends toaccumulate in hard to reach locations such as around the base of hairsand in the sulci of the skin's surface. As the fecal matter dehydratesupon exposure to the air, or upon contact with an absorbent cleansingimplement such as tissue paper, it adheres more tenaciously to the skinand hair, thus making subsequent removal of the remaining dehydratedsoil even more difficult.

Failure to remove fecal matter from the anal area can have a deleteriouseffect on personal hygiene. The fecal matter remaining on the skin afterpost-defecation cleansing has a high bacterial and viral content, ismalodorous and is generally dehydrated. These characteristics increasethe likelihood of perianal disorders and cause personal discomfort(e.g., itching, irritation, chafing, etc.). Further, the residual fecalmatter stains undergarments and causes unpleasant odors to emanate fromthe anal region. Thus, the consequences of inadequate perianal cleansingare clearly unattractive.

For those individuals suffering from anal disorders such as pruritisani, hemorrhoids, fissures, cryptitis, or the like, the importance ofadequate perianal cleansing takes on heightened significance. Perianaldisorders are usually characterized by openings in the skin throughwhich the bacteria and viruses in the residual fecal matter can readilyenter. Those people afflicted with anal disorders must, therefore,achieve a high degree of perianal cleansing after defecation or risk thelikely result that their disorders will be aggravated by the bacteriaand viruses remaining on the skin.

At the same time anal disorder sufferers face more severe consequencesfrom insufficient post defecation cleaning, they have greater difficultyin achieving a satisfactory level of soil removal. Anal disordersgenerally render the perianal region extremely sensitive and attempts toremove fecal matter from this region by wiping with even normal wipingpressure causes pain and can further irritate the skin. Attempts toimprove soil removal by increasing the wiping pressure can result inintense pain. Conversely, attempts to minimize discomfort by reducingthe wiping pressure result in an increased amount of residual fecalmatter left on the skin.

Conventional toilet tissue products used for anal cleaning areessentially dry, high density tissue papers that rely exclusively onmechanical processes to remove fecal matter from the perianal skin.These conventional products are rubbed against the perianal skin,typically with a pressure of about 1 psi (7 kilopascals) and basicallyscrape or abrade the fecal matter from the skin. After the first fewwipes, the upper portion of the soil layer is removed because the wipingprocess is able to overcome the soil-soil cohesive forces that existwithin the fecal matter. A cleavage is thereby created in the soil layeritself with the upper portion of the fecal layer being removed and thelower portion of the soil remaining adhered to the perianal skin.

Conventional tissue products are absorbent and with each successive wipethe fecal matter becomes increasingly dehydrated, causing it to adheremore tenaciously to the perianal skin and hair and making its removaldifficult in the extreme. Pressing the tissue forcefully against theperianal skin will remove more of the fecal matter but is intenselypainful for people suffering from anal disorders and can excoriate evennormal perianal skin, potentially causing irritation, inflammation,pain, bleeding, and infection.

Irritation and inflammation potentially caused by the use of tissueproducts is not limited to toilet tissue. Facial tissue products used towipe and remove nasal discharges associated with colds, flu andallergies can also cause such problems. In addition to difficulties inbreathing, seeing, and talking, an individual afflicted with thesedisorders frequently has a sore and irritated nose. The nose, as well asthe surrounding tissue, e.g., upper lip area, are often red and inflamedto the extent of becoming painful in extreme cases.

This irritation, inflammation and redness can have several causes. Aprime one is, of course, the sheer necessity of frequently blowing one'snose into the tissue, and wiping the resultant nasal discharge from thenose and surrounding area. The degree of irritation and inflammationcaused by such blowing and wiping is directly proportional to: (1) thesurface roughness of are in contact with the tissue. A tissue that isrelatively weak or relatively nonabsorbent requires a greater number ofcontacts with the face than a stronger or more absorbent tissue that isable to contain a greater quantity of nasal discharge.

There have been numerous previous attempts to reduce the abrasive effectof toilet and facial tissues and to increase their softness impression.One common approach is by mechanical processing. By using particularprocessing steps during papermaking, toilet and facial tissue productscan be made that are softer and less irritating. Examples of tissueproducts that are mechanically processed to be softer are shown in U.S.Pat. No 4,300,981 (Carstens), issued Nov. 17, 1981, as well as thevarious patents discussed in its specification.

Besides mechanical processing, others have applied emollients, salves,cleansing agents, and the like to tissue products to enhance not onlythe cleaning of the skin but also to reduce irritation and inflammation.This reduction in irritation and inflammation is typically achievedthrough either the lubricity of the substance applied to the tissue orthrough the therapeutic action of the substance itself. This approach isillustrated in U.S. Pat. No. 4,112,167 (Dake et al) issued Sep. 5, 1978,particularly in regard to toilet tissues. See also in U.S. Pat. No.3,896,807 (Buchalter), issued Jul. 29, 1975 and in U.S. Pat. No.3,814,096 (Weiss et al), issued Jun. 4, 1974 for other examples of thisapproach.

One substance that has been applied as a lotion to tissue products toimpart a soothing, lubricious feel is mineral oil. Mineral oil (alsoknown as liquid petrolatum) is a mixture of various liquid hydrocarbonsobtained by distilling the high-boiling (i.e., 300°-390° C.) fractionsin petroleum. Mineral oil is liquid at ambient temperatures, e.g.20°-25° C. As a result, mineral oil is relatively fluid and mobile, evenwhen applied to tissue products

Because mineral oil is fluid and mobile at ambient temperatures, ittends not to remain localized on the surface of the tissue, but insteadmigrates throughout. Accordingly, relatively high levels of mineral needto be applied to the tissue to provide the desired softness andlotion-like feel benefits. These levels can be as high as about 22-25wt. % of the tissue product. This leads not only to increased costs forthese lotioned tissue products, but other detrimental effects as well.

One of these detrimental effects is a decrease in tensile strength ofthe tissue product. As mineral oil migrates to the interior of thetissue, it tends to act as a debonding agent, thus decreasing thetensile strength of the product. This debonding effect becomes morepronounced as the level of mineral oil applied is increased. Increasingthe level of mineral oil applied can also adversely affect the caliperof the tissue product.

Even without increasing its level, the tendency of mineral oil tomigrate once applied has other detrimental effects. For example, theapplied mineral oil can transfer to, into and through the packaging orwrapper material for the lotioned toilet tissue product. This can createthe need for barrier-type packaging or wrapper films to avoid smearingor other leakage of mineral oil from the tissue product.

Accordingly, it would be desirable to provide lotioned tissue productsthat: (1) have a desirable soothing, lubricious feel; (2) do not requirerelatively high levels of mineral oil: (3) do not adversely affect thetensile strength and caliper of the product; and (4) do not requirespecial wrapping or barrier materials for packaging.

DISCLOSURE OF THE INVENTION

The present invention relates to a lotion composition that is semisolidor solid at ambient temperatures (i.e., at 20° C.) and imparts a soft,lubricious, lotion-like feel when applied to tissue paper. This lotioncomposition comprises:

(A) from about 20 to about 95% of a substantially water free emollienthaving a plastic or fluid consistency at 20° C. and comprising a memberselected from petroleum-based emollients, fatty acid ester emollients,alkyl ethoxylate emollients, and mixtures thereof; and

(B) from about 5 to about 80% of an agent capable of immobilizing theemollient on the surface of tissue paper treated with the lotioncomposition, the imobilizing agent having a melting point of at leastabout 40° C. and comprising a member selected from polyhydroxy fattyacid esters, polyhydroxy fatty acid amides, and mixtures thereof,wherein the polyhydroxy moiety of the ester or amide has at least twofree hydroxy groups; and

(C) optionally from about 2 to about 50% of a hydrophilic surfactanthaving an HLB value of at least about 7.

The present invention further relates to lotioned tissue papers whereinthe lotion composition is applied to at least one surface thereof in anamount of from about 2 to about 20% by weight of the dried tissue paper.Lotioned tissue papers according to the present invention have adesirable, lubricious, lotion-like feel. Because the emollient issubstantially immobilized on the surface of the tissue paper, lesslotion composition is needed to impart the desired soft, lotion-likefeel. As a result, the detrimental effects on the tensile strength andcaliper of the tissue caused by prior mineral oil-containing lotions canbe avoided. In addition, special barrier or wrapping materials areunnecessary in packaging the lotioned tissue products of the presentinvention.

As used herein, the term "comprising" means that the various components,ingredients, or steps, can be conjointly employed in practicing thepresent invention. Accordingly, the term "comprising" encompasses themore restrictive terms "consisting essentially of" and "consisting of."

All percentages, ratios and proportions used herein are by weight unlessotherwise specified.

A. Tissue Papers

The present invention is useful with tissue paper in general, includingbut not limited to conventionally felt-pressed tissue paper; high bulkpattern densified tissue paper; and high bulk, uncompacted tissue paper.The tissue paper can be of a homogenous or multi-layered construction;and tissue paper products made therefrom can be of a single-ply ormulti-ply construction. The tissue paper preferably has a basis weightof between about 10 g/m2 and about 65 g/m², and density of about 0.6g/cc or less. More preferably, the basis weight will be about 40 g/m² orless and the density will be about 0.3 g/cc or less. Most preferably,the density will be between about 0.04 g/cc and about 0.2 g/cc. SeeColumn 13, lines 61-67, of U.S. Pat. No. 5,059,282 (Ampulski et al),issued Oct. 22, 1991, which describes how the density of tissue paper ismeasured. (Unless otherwise specified, all amounts and weights relativeto the paper are on a dry basis.)

Conventionally pressed tissue paper and methods for making such paperare well known in the art. Such paper is typically made by depositing apapermaking furnish on a foraminous forming wire, often referred to inthe art as a Fourdrinier wire. Once the furnish is deposited on theforming wire, it is referred to as a web. The web is dewatered bypressing the web and drying at elevated temperature. The particulartechniques and typical equipment for making webs according to theprocess just described are well known to those skilled in the art. In atypical process, a low consistency pulp furnish is provided from apressurized headbox. The headbox has an opening for delivering a thindeposit of pulp furnish onto the Fourdrinier wire to form a wet web. Theweb is then typically dewatered to a fiber consistency of between about7% and about 25% (total web weight basis) by vacuum dewatering andfurther dried by pressing operations wherein the web is subjected topressure developed by opposing mechanical members, for example,cylindrical rolls. The dewatered web is then further pressed and driedby a steam drum apparatus known in the art as a Yankee dryer. Pressurecan be developed at the Yankee dryer by mechanical means such as anopposing cylindrical drum pressing against the web. Multiple Yankeedryer drums can be employed, whereby additional pressing is optionallyincurred between the drums. The tissue paper structures that are formedare referred to hereafter as conventional, pressed, tissue paperstructures. Such sheets are considered to be compacted since the entireweb is subjected to substantial mechanical compressional forces whilethe fibers are moist and are then dried while in a compressed state.

Pattern densified tissue paper is characterized by having a relativelyhigh bulk field of relatively low fiber density and an array ofdensified zones of relatively high fiber density. The high bulk field isalternatively characterized as a field of pillow regions. The densifiedzones are alternatively referred to as knuckle regions. The densifiedzones can be discretely spaced within the high bulk field or can beinterconnected, either fully or partially, within the high bulk field.The patterns can be formed in a nonornamental configuration or can beformed so as to provide an ornamental design(s) in the tissue paper.Preferred processes for making pattern densified tissue webs aredisclosed in U.S. Pat. No. 3,301,746 (Sanford et al), issued Jan. 31,1967; U.S. Pat. No. 3,974,025 (Ayers), issued Aug. 10, 1976; and U.S.Pat. No. 4,191,609 (Trokhan) issued Mar. 4, 1980; and U.S. Pat. No4,637,859 (Trokhan) issued Jan. 20, 1987; all of which are incorporatedby reference.

In general, pattern densified webs are preferably prepared by depositinga papermaking furnish on a foraminous forming wire such as a Fourdrinierwire to form a wet web and then juxtaposing the web against an array ofsupports. The web is pressed against the array of supports, therebyresulting in densified zones in the web at the locations geographicallycorresponding to the points of contact between the array of supports andthe wet web. The remainder of the web not compressed during thisoperation is referred to as the high bulk field. This high bulk fieldcan be further dedensified by application of fluid pressure, such aswith a vacuum type device or a blow-through dryer, or by mechanicallypressing the web against the array of supports. The web is dewatered,and optionally predried, in such a manner so as to substantially avoidcompression of the high bulk field. This is preferably accomplished byfluid pressure, such as with a vacuum type device or blow-through dryer,or alternately by mechanically pressing the web against an array ofsupports wherein the high bulk field is not compressed. The operationsof dewatering, optional predrying and formation of the densified zonescan be integrated or partially integrated to reduce the total number ofprocessing steps performed. Subsequent to formation of the densifiedzones, dewatering, and optional predrying, the web is dried tocompletion, preferably still avoiding mechanical pressing. Preferably,from about 8% to about 55% of the tissue paper surface comprisesdensified knuckles having a relative density of at least 125% of thedensity of the high bulk field.

The array of supports is preferably an imprinting carrier fabric havinga patterned displacement of knuckles that operate as the array ofsupports that facilitate the formation of the densified zones uponapplication of pressure. The pattern of knuckles constitutes the arrayof supports previously referred to. Suitable imprinting carrier fabricsare disclosed in U.S. Pat. No. 3,301,746 (Sanford et al), issued Jan.31, 1967; U.S. Pat. No. 3,821,068 (Salvucci et al), issued May 21, 1974;U.S. Pat. No. 3,974,025 (Ayers), issued Aug. 10, 1976; U.S. Pat. No.3,573,164 (Friedberg et al.), issued Mar. 30, 1971; U.S. Pat. No.3,473,576 (Amneus), issued Oct. 21, 1969; U.S. Pat. No. 4,239,065(Trokhan), issued Dec. 16, 1980; and U.S. Pat. No. 4,528,239 (Trokhan),issued Jul. 9, 1985, all of which are incorporated by reference.

Preferably, the furnish is first formed into a wet web on a foraminousforming carder, such as a Fourdrinier wire. The web is dewatered andtransferred to an imprinting fabric. The furnish can alternately beinitially deposited on a foraminous supporting carder that also operatesas an imprinting fabric. Once formed, the wet web is dewatered and,preferably, thermally predried to a selected fiber consistency ofbetween about 40% and about 80%. Dewatering is preferably performed withsuction boxes or other vacuum devices or with blow-through dryers. Theknuckle imprint of the imprinting fabric is impressed in the web asdiscussed above, prior to drying the web to completion. One method foraccomplishing this is through application of mechanical pressure. Thiscan be done, for example, by pressing a nip roll that supports theimprinting fabric against the face of a drying drum, such as a Yankeedryer, wherein the web is disposed between the nip roll and drying drum.Also, preferably, the web is molded against the imprinting fabric priorto completion of drying by application of fluid pressure with a vacuumdevice such as a suction box, or with a blow-through dryer. Fluidpressure can be applied to induce impression of densified zones duringinitial dewatering, in a separate, subsequent process stage, or acombination thereof.

Uncompacted, nonpattern-densified tissue paper structures are describedin U.S. Pat. No. 3,812,000 (Salvucci et al), issued May 21, 1974 andU.S. Pat. No. 4,208,459 (Becker et al), issued Jun. 17, 1980, both ofwhich are incorporated by reference. In general, uncompacted,nonpattern-densified tissue paper structures are prepared by depositinga papermaking furnish on a foraminous forming wire such as a Fourdrinierwire to form a wet web, draining the web and removing additional waterwithout mechanical compression until the web has a fiber consistency ofat least about 80%, and creping the web. Water is removed from the webby vacuum dewatering and thermal drying. The resulting structure is asoft but weak, high bulk sheet of relatively uncompacted fibers. Bondingmaterial is preferably applied to portions of the web prior to creping.

Compacted non-pattern-densified tissue structures are commonly known inthe art as conventional tissue structures. In general, compacted,non-pattern-densified tissue paper structures are prepared by depositinga papermaking furnish on a foraminous wire such as a Fourdrinier wire toform a wet web, draining the web and removing additional water with theaid of a uniform mechanical compaction (pressing) until the web has aconsistency of 25-50%, transferring the web to a thermal dryer such as aYankee and creping the web. Overall, water is removed from the web byvacuum, mechanical pressing and thermal means. The resulting structureis strong and generally of singular density, but very low in bulk,absorbency and softness.

The papermaking fibers utilized for the present invention will normallyinclude fibers derived from wood pulp. Other cellulosic fibrous pulpfibers, such as cotton linters, bagasse, etc., can be utilized and areintended to be within the scope of this invention. Synthetic fibers,such as rayon, polyethylene and polypropylene fibers, can also beutilized in combination with natural cellulosic fibers. One exemplarypolyethylene fiber that can be utilized is Pulpex®, available fromHercules, Inc. (Wilmington, Del.).

Applicable wood pulps include chemical pulps, such as Kraft, sulfite,and sulfate pulps, as well as mechanical pulps including, for example,groundwood, thermomechanical pulp and chemically modifiedthermomechanical pulp. Chemical pulps, however, are preferred since theyimpart a superior tactile sense of softness to tissue sheets madetherefrom. Pulps derived from both deciduous trees (hereafter, alsoreferred to as "hardwood") and coniferous trees (hereafter, alsoreferred to as "softwood") can be utilized. Also useful in the presentinvention are fibers derived from recycled paper, which can contain anyor all of the above categories as well as other non-fibrous materialssuch as fillers and adhesives used to facilitate the originalpapermaking.

In addition to papermaking fibers, the papermaking furnish used to maketissue paper structures can have other components or materials addedthereto as can be or later become known in the art. The types ofadditives desirable will be dependent upon the particular end use of thetissue sheet contemplated. For example, in products such as toiletpaper, paper towels, facial tissues and other similar products, high wetstrength is a desirable attribute. Thus, it is often desirable to add tothe papermaking furnish chemical substances known in the art as "wetstrength" resins.

A general dissertation on the types of wet strength resins utilized inthe paper art can be found in TAPPI monograph series No. 29, WetStrength in Paper and Paperboard, Technical Association of the Pulp andPaper Industry (New York, 1965). The most useful wet strength resinshave generally been cationic in character. For permanent wet strengthgeneration, polyamide-epichlorohydrin resins are cationic wet strengthresins have been found to be of particular utility. Suitable types ofsuch resins are described in U.S. Pat. No. 3,700,623 (Keim), issued Oct.24, 1972, and U.S. Pat. No. 3,772,076 (Keim), issued Nov. 13, 1973, bothof which are incorporated by reference. One commercial source of auseful polyamide-epichlorohydrin resin is Hercules, Inc. of Wilmington,Del., which markets such resins under the mark Kymene® 557H.

Polyacrylamide resins have also been found to be of utility as wetstrength resins. These resins are described in U.S. Pat. Nos. 3,556,932(Coscia et al), issued Jan. 19, 1971, and 3,556,933 (Williams et al),issued Jan. 19, 1971, both of which are incorporated herein byreference. One commercial source of polyacrylamide resins is AmericanCyanamid Co. of Stamford, Conn., which markets one such resin under themark Parez® 631 NC.

Still other water-soluble cationic resins finding utility in thisinvention are urea formaldehyde and melamine formaldehyde resins. Themore common functional groups of these polyfunctional resins arenitrogen containing groups such as amino groups and methylol groupsattached to nitrogen. Polyethylenimine type resins can also find utilityin the present invention. In addition, temporary wet strength resinssuch as Caldas 10 (manufactured by Japan Carlit) and CoBond 1000(manufactured by National Starch and Chemical Company) can be used inthe present invention. It is to be understood that the addition ofchemical compounds such as the wet strength and temporary wet strengthresins discussed above to the pulp furnish is optional and is notnecessary for the practice of the present invention.

In addition to wet strength additives, it can also be desirable toinclude in the papermaking fibers certain dry strength and lint controladditives known in the art. In this regard, starch binders have beenfound to be particularly suitable. In addition to reducing linting ofthe finished tissue paper product, low levels of starch binders alsoimpart a modest improvement in the dry tensile strength withoutimparting stiffness that could result from the addition of high levelsof starch. Typically the starch binder is included in an amount suchthat it is retained at a level of from about 0.01 to about 2%,preferably from about 0.1 to about 1%, by weight of the tissue paper.

In general, suitable starch binders for the present invention arecharacterized by water solubility, and hydrophilicity. Although it isnot intended to limit the scope of suitable starch binders,representative starch materials include corn starch and potato starch,with waxy corn starch known industrially as amioca starch beingparticularly preferred. Amioca starch differs from common corn starch inthat it is entirely amylopectin, whereas common corn starch containsboth amylopectin and amylose. Various unique characteristics of amiocastarch are further described in "Amioca--The Starch From Waxy Corn", H.H. Schopmeyer, Food Industries, December 1945, pp. 106-108 (Vol. pp.1476-1478).

The starch binder can be in granular or dispersed form, the granularform being especially preferred. The starch binder is preferablysufficiently cooked to induce swelling of the granules. More preferably,the starch granules are swollen, as by cooking, to a point just prior todispersion of the starch granule. Such highly swollen starch granulesshall be referred to as being "fully cooked." The conditions fordispersion in general can vary depending upon the size of the starchgranules, the degree of crystallinity of the granules, and the amount ofamylose present. Fully cooked amioca starch, for example, can beprepared by heating an aqueous slurry of about 4% consistency of starchgranules at about 190° F. (about 88° C.) for between about 30 and about40 minutes. Other exemplary starch binders that can be used includemodified cationic starches such as those modified to have nitrogencontaining groups, including amino groups and methylol groups attachedto nitrogen, available from National Starch and Chemical Company,(Bridgewater, N.J.), that have previously been used as pulp furnishadditives to increase wet and/or dry strength.

B. Lotion Composition.

The lotion compositions of the present invention are solid, or moreoften semisolid, at 20° C., i.e. at ambient temperatures. By "semisolid"is meant that the lotion composition has a theology typical ofpseudoplastic or plastic fluids. When no shear is applied, the lotioncompositions can have the appearance of a semi-solid but can be made toflow as the shear rate is increased. This is due to the fact that, whilethe lotion composition contains primarily solid components, it alsoincludes some minor liquid components.

By being solid or semisolid at ambient temperatures, these lotioncompositions do not have a tendency to flow and migrate into theinterior of the tissue web to which they are applied. This means lesslotion composition is required for imparting softness and lotion-likefeel benefits. It also means there less chance for debonding of thetissue paper that can potentially lead to decreases in tensile strength.

When applied to tissue paper, the lotion compositions of the presentinvention impart a soft, lubricious, lotion like feel to the user of thepaper. This particular feel has also been characterized as "silky","slick", "smooth", etc. Such a lubricious, lotion-like feel isparticularly beneficial for those having more sensitive skin due tochronic conditions such as skin dryness or hemorrhoids, or due to moretransient conditions such as colds or allergies.

The lotion compositions of the present invention comprise: (1) anemollient: (2) an immobilizing agent for the emollient; (3) optionally ahydrophilic surfactant; and (4) other optional components:

1. Emollient

The key active ingredient in these lotion compositions is one or moreemollients. As used herein, an emollient is a material that softens,soothes, supples, coats, lubricates, moisturizes, or cleanses the skin.An emollient typically accomplishes several of these objectives such assoothing, moisturizing, and lubricating the skin. For the purposes ofthe present invention, these emollients have either a plastic or fluidconsistency at 20° C., i.e., at ambient temperatures. This particularemollient consistency allows the lotion composition to impart a soft,lubricious, lotion-like feel.

The emollients useful in the present invention are also substantiallyfree of water. By "substantially free of water" is meant that water isnot intentionally added to the emollient. Addition of water to theemollient is not necessary in preparing or using the lotion compositionsof the present invention and could require an additional drying step.However, minor or trace quantities of water in the emollient that arepicked as a result of, for example, ambient humidity can be toleratedwithout adverse effect. Typically, the emollients used in the presentinvention contain about 3% or less water, preferably about 1% or lesswater, most preferably about 0.5% or less water.

Emollients useful in the present invention can be petroleum-based, fattyacid ester type, alkyl ethoxylate type, or mixtures of these emollients.Suitable petroleum-based emollients include those hydrocarbons, ormixtures of hydrocarbons, having chain lengths of from 16 to 32 carbonatoms. Petroleum based hydrocarbons having these chain lengths includemineral oil (also known as "liquid petrolatum") and petrolatum (alsoknown as "mineral wax," "petroleum jelly" and "mineral jelly"). Mineraloil usually refers to less viscous mixtures of hydrocarbons having from16 to 20 carbon atoms. Petrolatum usually refers to more viscousmixtures of hydrocarbons having from 16 to 32 carbon atoms. Petrolatumis a particularly preferred emollient for lotion compositions of thepresent invention.

Suitable fatty acid ester type emollients include those derived from C₁₂-C₂₈ fatty acids, preferably C₁₆ -C₂₂ saturated fatty acids, and shortchain (C₁ -C₈, preferably C₁ -C₃) monohydric alcohols. Representativeexamples of such esters include methyl palmitate, methyl stearate,isopropyl laurate, isopropyl myristate, isopropyl palmitate, andethylhexyl palmitate. Suitable fatty acid ester emollients can also bederived from esters of longer chain fatty alcohols (C₁₂ -C₂₈, preferablyC₁₂ -C₁₆) and shorter chain fatty acids e.g., lactic acid, such aslauryl lactate and cetyl lactate.

Suitable alkyl ethoxylate type emollients include C₁₂ -C₁₈ fatty alcoholethoxylates having an average of from 3 to 30 oxyethylene units,preferably from about 4 to about 23. Representative examples of suchalkyl ethoxylates include laureth-3 (a lauryl ethoxylate having anaverage of 3 oxyethylene units), laureth-23 (a lauryl ethoxylate havingan average of 23 oxyethylene units), ceteth-10 (acetyl ethoxylate havingan average of 10 oxyethylene units) and steareth-10 (a stearylethoxylate having an average of 10 oxyethylene units). These alkylethoxylate emollients are typically used in combination with thepetroleum-based emollients, such as petrolatum, at a weight ratio ofalkyl ethoxylate emollient to petroleum-based emollient of from about1:1 to about 1:3, preferably from about 1:1.5 to about 1:2.5.

Besides petroleum-based emollients, fatty acid ester emollients andalkyl ethoxylate emollients, the emollients useful in the presentinvention can include minor amounts (e.g., up to about 10% of the totalemollient) of other, conventional emollients. These other, conventionalemollients include propylene glycol, glycerine, triethylene glycol,spermaceti or other waxes, fatty acids, fatty alcohols and fatty alcoholethers having from 12 to 28 carbon atoms in their fatty chain, such asstearic acid, cetyl alcohol, propoxylated fatty alcohols; glycerides,acetoglycerides, and ethoxylated glycerides of C₁₂ -C₂₈ fatty acids;other fatty esters of polyhydroxy alcohols; lanolin and its derivatives;and polysiloxanes having a viscosity at 20° C. of from about 5 to about2,000 centistokes such as disclosed in U.S. Pat. No. 5,059,282 (Ampulskiet al), issued Oct. 22, 1991, which is incorporated by reference. Theseother emollients should be included in a manner such that the solid orsemisolid characteristics of the lotion composition are maintained.

The amount of emollient that can be included in the lotion compositionwill depend on a variety of factors, including the particular emollientinvolved, the lotion-like benefits desired, the other components in thelotion composition and like factors. The lotion composition can comprisefrom about 20 to about 95% of the emollient. Preferably, the lotioncomposition comprises from about 40 to about 80%, most preferably fromabout 50 to about 75%, of the emollient.

2. Immobilizing Agent

An especially key component of the lotion compositions of the presentinvention is an agent capable of immobilizing the emollient on thesurface of the paper to which the lotion composition is applied. Becausethe emollient in the composition has a plastic or fluid consistency at20° C., it tends to flow or migrate, even when subjected to modestshear. When applied to a tissue paper web, especially in a melted ormolten state, the emollient will not remain primarily on the surface ofthe paper. Instead, the emollient will tend to migrate and flow into theinterior of the paper web.

This migration of the emollient into the interior of the web can causeundesired debonding of the paper by interfering with the normal hydrogenbonding that takes place between the paper fibers. This usually leads toa decrease in tensile strength of the paper. It also means much moreemollient has to be applied to the paper web to get the desiredlubricious, lotion-like feel benefits. Increasing the level of emollientnot only increases the cost, but also exacerbates the debonding problemof the paper.

The immobilizing agent counteracts this tendency of the emollient tomigrate or flow by keeping the emollient primarily localized on thesurface of the tissue paper web to which the lotion composition isapplied. This is believed to be due to the fact that the immobilizingagent forms hydrogen bonds with the tissue paper web. Through thishydrogen bonding, the immobilizing agent becomes localized on thesurface of the paper. Since the immobilizing agent is also miscible withthe emollient (or solubilized in the emollient with the aid of anappropriate emulsifier), it entraps the emollient on the surface of thepaper as well.

In addition to being miscible with (or solubilized in) the emollient,the immobilizing agent needs to have a melting point of at least about40° C. This is so the immobilizing agent itself will not have a tendencyto migrate or flow. Preferred immobilizing agents will have meltingpoints of at least about 50° C. Typically, the immobilizing agent willhave a melting point in the range of from about 50° to about 150° C.

Suitable immobilizing agents for the present invention can comprisepolyhydroxy fatty acid esters, polyhydroxy fatty acid amides, andmixtures thereof. To be useful as immobilizing agents, the polyhydroxymoiety of the ester or amide has to have at least two free hydroxygroups. It is believed that these free hydroxy groups are the ones thatco-crosslink through hydrogen bonds with the cellulosic fibers of thetissue paper web to which the lotion composition is applied andhomo-crosslink, also through hydrogen bonds, the hydroxy groups of theester or amide, thus entrapping and immobilizing the other components inthe lotion matrix. Preferred esters and amides will have three or morefree hydroxy groups on the polyhydroxy moiety and are typically nonionicin character. Because of the skin sensitivity of those using paperproducts to which the lotion composition is applied, these esters andamides should also be relatively mild and non-irritating to the skin.

Suitable polyhydroxy fatty acid esters for use in the present inventionwill have the formula: ##STR1## wherein R is a C₅ -C₃₁ hydrocarbylgroup, preferably straight chain C₇ -C₁₉ alkyl or alkenyl, morepreferably straight chain C₉ -C₁₇ alkyl or alkenyl, most preferablystraight chain C₁₁ -C₁₇ alkyl or alkenyl, or mixture thereof; Y is apolyhydroxyhydrocarbyl moiety having a hydrocarbyl chain with at least 2free hydroxyls directly connected to the chain; and n is at least 1.Suitable Y groups can be derived from polyols such as glycerol,pentaerythritol; sugars such as raffinose, maltodextrose, galactose,sucrose, glucose, xylose, fructose, maltose, lactose, mannose anderythrose; sugar alcohols such as erythritol, xylitol, malitol, mannitoland sorbitol; and anhydrides of sugar alcohols such as sorbitan.

One class of suitable polyhydroxy fatty acid esters for use in thepresent invention comprises certain sorbitan esters, preferably thesorbitan esters of C₁₆ -C₂₂ saturated fatty acids. Because of the mannerin which they are typically manufactured, these sorbitan esters usuallycomprise mixtures of mono-, di-, tri-, etc. esters. Representativeexamples of suitable sorbitan esters include sorbitan palmitates (e.g.,SPAN 40), sorbitan stearates (e.g., SPAN 60), and sorbitan behenates,that comprise one or more of the mono-, di- and tri-ester versions ofthese sorbitan esters, e.g., sorbitan mono-, di- and tri-palmitate,sorbitan mono-, di- and tri-stearate, sorbitan mono-, di andri-behenate, as well as mixed tallow fatty acid sorbitan mono-, di- andtri-esters. Mixtures of different sorbitan esters can also be used, suchas sorbitan palmitates with sorbitan stearates. Particularly preferredsorbitan esters are the sorbitan stearates, typically as a mixture ofmono-, di- and tri-esters (plus some tetraester) such as SPAN 60, andsorbitan stearates sold under the trade name GLYCOMUL-S by Lonza, Inc.Although these sorbitan esters typically contain mixtures of mono-, di-and tri-esters, plus some tetraester, the mono-and di-esters are usuallythe predominant species in these mixtures.

Another class of suitable polyhydroxy fatty acid esters for use in thepresent invention comprises certain glyceryl monoesters, preferablyglyceryl monoesters of C₁₆ -C₂₂ saturated fatty acids such as glycerylmonostearate, glyceryl monopalmitate, and glyceryl monobehenate. Again,like the sorbitan esters, glyceryl monoester mixtures will typicallycontain some di- and triester. However, such mixtures should containpredominantly the glyceryl monoester species to be useful in the presentinvention.

Another class of suitable polyhydroxy fatty acid esters for use in thepresent invention comprise certain sucrose fatty acid esters, preferablythe C₁₂ -C₂₂ saturated fatty acid esters of sucrose. Sucrose monoestersare particularly preferred and include sucrose monostearate and sucrosemonolaurate.

Suitable polyhydroxy fatty acid amides for use in the present inventionwill have the formula: ##STR2## wherein R¹ is H, C₁ -C₄ hydrocarbyl,2-hydroxyethyl, 2-hydroxypropyl, methoxyethyl, methoxypropyl or amixture thereof, preferably C₁ -C₄ alkyl, methoxyethyl or methoxypropyl,more preferably C₁ or C₂ alkyl or methoxypropyl, most preferably C₁alkyl (i.e., methyl) or methoxypropyl; and R² is a C₅ -C₃₁ hydrocarbylgroup, preferably straight chain C₇ -C₁₉ alkyl or alkenyl, morepreferably straight chain C₉ -C₁₇ alkyl or alkenyl, most preferablystraight chain C₁₁ -C₁₇ alkyl or alkenyl, or mixture thereof, and Z is apolyhydroxyhydrocarbyl moiety having a linear hydrocarbyl chain with atleast 3 hydroxyls directly connected to the chain. See U.S. Pat. No.5,174,927 (Honsa), issued Dec. 29, 1992 (herein incorporated byreference) which discloses these polyhydroxy fatty acid amides, as wellas their preparation.

The Z moiety preferably will be derived from a reducing sugar in areductive amination reaction; most preferably glycityl. Suitablereducing sugars include glucose, fructose, maltose, lactose, galactose,mannose, and xylose. High dextrose corn syrup, high fructose corn syrup,and high maltose corn syrup can be utilized, as well as the individualsugars listed above. These corn syrups can yield mixtures of sugarcomponents for the Z moiety.

The Z moiety preferably will be selected from the group consisting of--CH₂ --(CHOH)_(n) --CH₂ OH, --CH(CH₂ OH)--[(CHOH)_(n--1) ]--CH₂ OH,--CH₂ OH --CH₂ --(CHOH)₂ (CHOR³)(CHOH)--CH₂ OH, where n is an integerfrom 3 to 5, and R³ is H or a cyclic or aliphatic monosaccharide. Mostpreferred are the glycityls where n is 4, particularly --CH₂ --(CHOH)₄--CH₂ OH.

In the above formula, R¹ can be, for example, N-methyl, N-ethyl,N-propyl, N-isopropyl, N-butyl, N-2-hydroxyethyl, N-methoxypropyl orN-2-hydroxypropyl,. R² can be selected to provide, for example,cocamides, stearamides, oleamides, lauramides, myristamides,capricamides, palmitamides, tallowamides, etc. The Z moiety can be1-deoxyglucityl, 2-deoxyfructityl, 1-deoxymaltityl, 1-deoxylactityl,1-deoxygalactityl, 1-deoxymannityl, 1-deoxymaltotriotityl, etc.

The most preferred polyhydroxy fatty acid amides have the generalformula: ##STR3## wherein R¹ is methyl or methoxypropyl; R² is a C₁₁-C₁₇ straight-chain alkyl or alkenyl group. These includeN-lauryl-N-methyl glucamide, N-lauryl-N-methoxypropyl glucamide,N-cocoyl-N-methyl glucamide, N-cocoyl-N-methoxypropyl glucamide,N-palmityl-N-methoxypropyl glucamide, N-tallowyl-N-methyl glucamide, orN-tallowyl-N-methoxypropyl glucamide.

As previously noted, some of the immobilizing agents require anemulsifier for solubilization in the emollient. This is particularly thecase for certain of the glucamides such as the N-alkyl-N-methoxypropylglucamides having HLB values of at least about 7. Suitable emulsifierswill typically include those having HLB values below about 7. In thisregard, the sorbitan esters previously described, such as the sorbitanstearates, having HLB values of about 4.9 or less have been found usefulin solubilizing these glucamide immobilizing agents in petrolatum. Othersuitable emulsifiers include steareth-2 (polyethylene glycol ethers ofstearyl alcohol that conform to the formula CH₃ (CH₂)₁₇ (OCH₂ CH₂)_(n)OH, where n has an average value of 2), sorbitan tristearate, isosorbidelaurate, and glyceryl monostearate. The emulsifier can be included in anamount sufficient to solubilize the immobilizing agent in the emollientsuch that a substantially homogeneous mixture is obtained. For example,an approximately 1:1 mixture of N-cocoyl-N-methyl glucamide andpetrolatum that will normally not melt into a single phase mixture, willmelt into a single phase mixture upon the addition of 20% of a 1:1mixture of steareth-2 and sorbitan tristearate as the emulsifier.

The amount of immobilizing agent that should be included in the lotioncomposition will depend on a variety of factors, including theparticular emollient involved, the particular immobilizing agentinvolved, whether an emulsifier is required to solubilize theimmobilizing agent in the emollient, the other components in the lotioncomposition and like factors. The lotion composition can comprise fromabout 5 to about 80% of the immobilizing agent. Preferably, the lotioncomposition comprises from about 5 to about 50%, most preferably fromabout 10 to about 40%, of the immobilizing agent.

3. Optional Hydrophilic Surfactant

In many instances, lotion compositions according to the presentinvention will be applied to tissue paper webs that will be used astoilet tissue. In such cases, it is highly desirable that the paper webtreated with the lotion composition be sufficiently wettable. Dependingupon the particular immobilizing agent used in the lotion composition ofthe present invention, an additional hydrophilic surfactant (or amixture of hydrophilic surfactants) may, or may not, be required toimprove wettability. For example, some immobilizing agents, such asN-cocoyl-N-methoxypropyl glucamide have HLB values of at least about 7and are sufficiently wettable without the addition of hydrophilicsurfactant. Other immobilizing agents such the sorbitan stearates havingHLB values below about 7 will require addition of hydrophilic surfactantto improve wettability if the lotion composition is applied to paperwebs used as toilet tissue.

Suitable hydrophilic surfactants will be miscible with the emollient andthe immobilizing agent so as to form homogeneous mixtures. Because ofthe skin sensitivity of those using paper products to which the lotioncomposition is applied, these surfactants should also be relatively mildand non-irritating to the skin. Typically, these hydrophilic surfactantsare nonionic to be not only non-irritating to the skin, but also avoidother undesirable effects on the tissue paper, e.g., reductions intensile strength.

Suitable nonionic surfactants will be substantially nonmigratory afterthe lotion composition is applied to the tissue paper web and willtypically have HLB values in the range of from about 8 to about 23. Tobe nonmigratory, these nonionic surfactants will typically have melttemperatures greater than the temperatures commonly encountered duringstorage, shipping, merchandising, and use of tissue paper products,e.g., at least about 30° C. In this regard, these nonionic surfactantswill preferably have melting points similar to those of the immobilizingagents previously described.

Suitable nonionic surfactants for use in lotion compositions of thepresent invention include alkylglycosides; alkylglycoside ethers asdescribed in U.S. Pat. No. 4,011,389 (Langdon, et al), issued Mar. 8,1977; alkylpolyethoxylated esters such as Pegosperse 1000MS (availablefrom Lonza, Inc., Fair Lawn, N.J.), ethoxylated sorbitan mono-, di-and/or tri-esters of C₁₂ -C₁₈ fatty acids having an average degree ofethoxylation of from about 2 to about 20, preferably from about 2 toabout 10, such as TWEEN 60 (sorbitan esters of stearic acid having aaverage degree of ethoxylation of about 20) and TWEEN 61 (sorbitanesters of stearic acid having an average degree of ethoxylation of about4), and the condensation products of aliphatic alcohols with from about1 to about 54 moles of ethylene oxide. The alkyl chain of the aliphaticalcohol is typically in a straight chain (linear) configuration andcontains from about 8 to about 22 carbon atoms. Particularly preferredare the condensation products of alcohols having an alkyl groupcontaining from about 11 to about 18 carbon atoms with from about 3 toabout 30 moles of ethylene oxide per mole of alcohol. Examples of suchethoxylated alcohols include the condensation products of myristylalcohol with 7 moles of ethylene oxide per mole of alcohol, thecondensation products of coconut alcohol (a mixture of fatty alcoholshaving alkyl chains varying in length from 10 to 14 carbon atoms) withabout 6 moles of ethylene oxide. A number of suitable ethoxylatedalcohols are commercially available, including TERGITOL 15-S-9 (thecondensation product of C₁₁ -C₁₅ linear alcohols with 9 moles ofethylene oxide), marketed by Union Carbide Corporation; KYRO EOB(condensation product of C₁₃ -C₁₅ linear alcohols with 9 moles ofethylene oxide), marketed by The Procter & Gamble Co., the NEODOL brandname surfactants marketed by Shell Chemical Co., in particular NEODOL25-12 (condensation product of C₁₂ -C₁₅ linear alcohols with 12 moles ofethylene oxide) and NEODOL 23-6.5T (condensation product of C₁₂ -C₁₃linear alcohols with 6.5 moles of ethylene oxide that has been distilled(topped) to remove certain impurities), and especially the PLURAFACbrand name surfactants marketed by BASF Corp., in particular PLURAFACA-38 (a condensation product of a C₁₈ straight chain alcohol with 27moles of ethylene oxide). (Certain of the hydrophilic surfactants, inparticular ethoxylated alcohols such as NEODOL 25-12, can also functionas alkyl ethoxylate emollients).

The amount of hydrophilic surfactant required to increase thewettability of the lotion composition to a desired level will dependupon the HLB value and level of immobilizing agent used, the HLB valueof the surfactant used and like factors. The lotion composition cancomprise from about 2 to about 50% of the hydrophilic surfactant whenneeded to increase the wettability properties of the composition.Preferably, the lotion composition comprises from about 2 to about 20%,most preferably from about 5 to about 15%, of the hydrophilic surfactantwhen needed to increase weltability.

4. Other Optional Components

Lotion compositions can comprise other optional components typicallypresent in emollient, creams, and lotions of this type. These optionalcomponents include perfumes, disinfectant antibacterial actives,pharmaceutical actives, film formers, deodorants, opacifiers,astringents, solvents and the like. In addition, stabilizers can beadded to enhance the shelf life of the lotion composition such ascellulose derivatives, proteins and lecithin. All of these materials arewell known in the art as additives for such formulations and can beemployed in appropriate amounts in the lotion compositions of thepresent invention.

C. Treating Tissue Paper With Lotion Composition

In preparing lotioned paper products according to the present invention,the lotion composition is applied to at least one surface of a tissuepaper web. Any of a variety of application methods that evenlydistribute lubricious materials having a molten or liquid consistencycan be used. Suitable methods include spraying, printing (e.g.,flexographic printing), coating (e.g., gravure coating), extrusion, orcombinations of these application techniques, e.g. spraying the lotioncomposition on a rotating surface, such as a calender roll, that thentransfers the composition to the surface of the paper web. The lotioncomposition can be applied either to one surface of the tissue paperweb, or both surfaces. Preferably, the lotion composition is applied toboth surfaces of the paper web.

The manner of applying the lotion composition to the tissue paper webshould be such that the web does not become saturated with the lotioncomposition. If the web becomes saturated with the lotion composition,there is a greater potential for debonding of the paper to occur, thusleading to a decrease in the tensile strength of the paper. Also,saturation of the paper web is not required to obtain the softness andlotion-like feel benefits from the lotion composition of the presentinvention. Particularly suitable application methods will apply thelotion composition primarily to the surface, or surfaces of the paperweb.

The lotion composition can be applied to the tissue paper web after theweb has been dried, i.e. a "dry web" addition method. The lotioncomposition is applied in an amount of from about 2 to about 20% byweight of the tissue paper web. Preferably, the lotion composition isapplied in an amount of from about 5 to about 15% by weight of thetissue paper web, most preferably from about 5 to about 10% by weight ofthe web. Such relatively low levels of lotion composition are adequateto impart the desired softness and lotion-like feel benefits to thetissue paper, yet do not saturate the tissue paper web to such an extentthat absorbency, wettability and particularly, strength, aresubstantially affected.

The lotion composition can also be applied nonuniformly to thesurface(s) of the tissue paper web. By "nonuniform" is meant that theamount, pattern of distribution, etc. of the lotion composition can varyover the surface of the paper. For example, some portions of the surfaceof the tissue paper web can have greater or lesser amounts of lotioncomposition, including portions of the surface that do not have anylotion composition on it.

The lotion composition can be applied to the tissue paper web at anypoint after it has been dried. For example, the lotion composition canbe applied to the tissue paper web after it has been creped from aYankee dryer, but prior to calendering, i.e., before being passedthrough calender rolls. The lotion composition can also be applied tothe paper web after it has passed through such calender rolls and priorto being wound up on a parent roll. Usually, it is preferred to applythe lotion composition to the tissue paper as it is being unwound from aparent roll and prior to being wound up on smaller, finished paperproduct rolls.

The lotion composition is typically applied from a melt thereof to thetissue paper web. Since the lotion composition melts at significantlyabove ambient temperatures, it is usually applied as a heated coating tothe tissue paper web. Typically, the lotion composition is heated to atemperature in the range from about 35° to about 100° C., preferablyfrom 40° to about 90° C., prior to being applied to the tissue paperweb. Once the melted lotion composition has been applied to the tissuepaper web, it is allowed to cool and solidify to form solidified coatingor film on the surface of the paper.

In applying lotion compositions of the present invention to tissue paperwebs, gravure coating and extrusion coating methods are preferred. FIG.1 illustrates one such preferred method involving gravure coating.Referring to FIG. 1, a dried tissue web 1 is unwound from parent tissueroll 2 (rotating in the direction indicated by arrow 2a) and advancedaround turning roll 4. From turning roll 4, web 1 is advanced to gravurecoating station 6 where the lotion composition is then applied to bothsides of the web. After leaving station 6, web 1 becomes a lotioned webindicated by 3. Lotioned web 3 is then advanced around turning roll 8and then wound up on lotioned tissue parent roll 10 (rotating in thedirection indicated by arrow 10a).

Station 6 comprises a pair of linked offset gravure presses 12 and 14.Press 12 consists of a lower gravure cylinder 16 and an upper offsetcylinder 18; press 14 similarly consists of a lower gravure cylinder 20and an upper offset cylinder 22. Gravure cylinders 16 and 20 each have achrome plated surface, while offset cylinders 18 and 22 each have apolyurethane rubber surface. These gravure and offset cylinders rotatein the directions indicated by arrows 16a, 18a, 20a and 22a,respectively. As shown in FIG. 1, offset cylinders 18 and 22 are opposedto one another and provide a nip area indicated by 23 through which web1 passes.

Positioned beneath gravure cylinders 16 and 20 are fountain trays 24 and26, respectively. Hot, molten (e.g., 65° C.) lotion composition ispumped into each of these heated trays 24 and 26 to provide reservoirsof the molten lotion composition, as indicated arrows by 30 and 32,respectively. As gravure cylinders 16 and 20 rotate in the directionsindicated by arrows 16a and 20a within reservoirs 30 and 32, they pickup a quantity of molten lotion composition. Excess lotion on each of thegravure cylinders 16 and 20 is then removed by doctor blades 34 and 36,respectively.

The lotion composition remaining on gravure cylinders 16 and 20 is thentransferred to heated offset cylinders 18 and 22 (rotating in theopposite direction as indicated by arrows 18a and 22b) in nip areas 38and 40 between the respective pairs of cylinders. The lotion compositiontransferred to offset cylinders 18 and 22 is then transferred to theopposite sides of web 1. The amount of lotion composition transferred toweb 1 can be controlled by: (1) adjusting the width of nip area 23between offset cylinders 18 and 22; and/or (2) adjusting the width ofnip areas 38 and 40 between gravure/offset cylinder pairs 16/18 and20/22.

FIG. 2 illustrates an alternative preferred method involving slotextrusion coating. Referring to FIG. 2, a dried tissue web 101 isunwound from parent tissue roll 102 (rotating in the direction indicatedby arrow 102a) and then advanced around turning roll 104. From turningroll 104, web 101 is advanced to slot extrusion coating station 106where the lotion composition is then applied to both sides of the web.After leaving station 106, web 101 becomes a lotioned web indicated by103. Lotioned web 103 is then wound up on lotioned tissue parent roll110 (rotating in the direction indicated by arrow 110a).

Station 106 comprises a pair of spaced slot extruders 112 and 114.Extruder 112 has an elongated slot 116 and a web contacting surface 118;extruder 114 similarly has an elongated slot 120 and a web contactingsurface 122. As shown in FIG. 2, extruders 112 and 114 are oriented suchthat surface 118 is in contact with one side of web 101, while surface122 is in contact with the other side of web 101. Hot, molten (e.g., 65°C.) lotion composition is pumped to each of extruders 112 and 114 and isthen extruded through slots 116 and 120, respectively.

As web 101 passes over the heated surface 118 of extruder 112 andreaches slot 116, the molten lotion composition extruded from slot 116is applied to the side of web 101 in contact with surface 118.Similarly, as web 101 passes over heated surface 122 of extruder 114 andreaches slot 120, the molten lotion composition extruded from slot 120is applied to the side of web 101 in contact with surface 122. Theamount of lotion composition transferred to web 101 is controlled by:(1) the rate at which the molten lotion composition is extruded fromslots 116 and 122; and/or (2) the speed at which web 101 travels whilein contact with surfaces 118 and 122.
